Certain patients with conductive or mixed hearing loss can benefit from bone-conduction hearing devices or active middle ear implants. Available devices differ in coupling site, energy transfer from the sound processor to the implant, and the active or passive actuator technology. The audiological benefit of those devices depends on the maximum stable power output and the noise floor of the device, the degree and expected stability of the sensorineural hearing loss and the coupling efficiency with the aim on achieving a minumum of 30-35 dB effective dynamic range. The choice of the device is often a trade-off between the optimal audiological solution with respect to the hearing loss, technical device-related parameters and the expected coupling efficiency, the optimal surgical solution with respect to patho-anatomical aspects, device dimensions and the coupling site, invasiveness or surgical risks, and other patient factors with respect to the patients' wish and expectations, social aspects, device usability and connectivity. This review article lists all currently available implantable and conventional bone-conduction hearing devices and active middle ear implants with respect to technical features like maximum power output, market availability, and the expected effective output dynamic range.
某些传导性或混合性听力损失的患者可以从骨导听力设备或主动中耳植入物中受益。现有的设备在耦合部位、声音处理器到植入物的能量传递以及主动或被动执行器技术方面有所不同。这些设备的听力学获益取决于设备的最大稳定功率输出和噪声底，传感器神经性听力损失的程度和预期稳定性以及与实现最小 30-35dB 有效动态范围的目标的耦合效率。设备的选择通常是在针对听力损失的最佳听力学解决方案、技术设备相关参数和预期的耦合效率、针对病理解剖方面、设备尺寸和耦合部位、侵入性或手术风险以及其他患者因素（如患者的意愿和期望、社会方面、设备可用性和连接性）之间的权衡。本文列出了所有目前可植入和传统的骨导听力设备和主动中耳植入物，涉及最大功率输出、市场可用性和预期有效输出动态范围等技术特征。
